Eh, I don't really notice a difference in speed between 2.1 and 2.2, not even a difference in battery life. 2.1 was faster internet access wise than 2.2 though. BTW, I only have 2, yes, 2 extra apps installed; setCPU and WeatherBug. Also, i have tried other radio basebands too, it just seems my Droid likes 2.1 better.
